Clarification on the requirements for BB: Chicken - slaughter and clean

The requirements for the "Harvest a Chicken - animal care.sand.chickenharvest" PEP BB says it must be "Killed in a humane manner".  Is chopping an inverted chickens head off with an axe acceptable for this BB?  The example videos show restraining the bird and cutting the neck partway.  Is that considered more humane than a swift chop with the axe?  I'm not arguing that it isn't - I just want to understand the reasoning and the requirement.

I think this one's hard, especially with older/larger birds. My husband did the slice-the-neck thing on our first drakes--they were like 12 weeks old, and it went fine. He tried it on an older drake a year or two later, and the drake wouldn't die. It kept writhing and it was traumatic. It took him 4 or more tries to end the duck. It was not  very humane...and he's refused to harvest a duck since. I don't blame him.

I also was a neighbor's house, and they were trying to harvest their turkey. It did not go well. The turkey didn't die quickly and in the end they had to try to chop the head off while it was in the kill cone.

I think if you can love on that chicken and give it a nice, swift end, it doesn't matter if it's the next slit or the head chop, as long as it's fast for the bird.

Do you have any thoughts on why it was less successful on those other two attempts? Knife not as sharp? Cut not in the right place?

I think for the purposes of this BB, as thoughtful and humane as you can manage should do the trick.  Slaughtering it at home so it isn't transported somewhere strange is a good step.
